Welcome to the forum and thanks for your question.  I'll be glad to comment.  Your recent symptoms following the cut you experienced are coincidental and not due to HIV or any other illness you might have acquired during your interactions you describe with the CSWs.  When cuts such as the one you describe occur they begin to seal up almost immediately, preventing access of microbes from the environment from access your blood stream.  If either of the CSWs you interacted with had HIV (still unlikely from a statistical perspective), their virus would not have accessed your blood stream to cause infection.  These are no risk exposures which are not medical indications for concern or for HIV testing.  

As you point out, as travelers it is quite common to pick up circulating viruses.  I suspect that is what has happened.  You are not going to be the first person to acquire HIV form these sorts of exposures.  EWH

To follow on,

1 - regarding HIV in vaginal secretions - is their a difference between fingering and external masturbation of a female partner?

2 - on a popular website it claims there are no HIV particles in lubricating fluids released from bartholins glands during masturbation of a female partner.

3 - why cant HIV particles be forced into the wound with severe vigorous rubbing?

4 - what kind of wounds would be susceptible, a popular website states even a freshly  amputated finger inserted into a HIV persons vagina would not be a significant risk?

I think you are over-thinking this

1. No, the risk of exposure (none) is comparable whether the exposure takes place inside a partner's vaginal or due to external contact.

2.  "Popular websites" and the internet in general are a notorious source of misinformation.  I know of no credible data to suggest that secretions from a Batholin;s gland would not be infectious.

3.  There are multiple factors in play here including that the blood vessel integrity which prevents bleeding also prevents access, that when bleedin occurs, the flow is out, not inward, and finally, the environmental exposure eliminates infectivity virtually immediately.

4.  None that I am aware of.  The person involved in the fanciful situation you mention would have more to worry about than masturbating  partner.

My advice to you is to stay off the internet and to not worry about the events you describe.  You are not going to be the 1rst person to acquire HIV form a paper cut  EWH

This will be my final post. To confirm my understanding of your responses.

1 - A cut on a finger involving foil from a medication blister pack is still classified as a 'paper cut' even though it is thicker and even if bleeding occurred.

2 - Such 'paper cuts' if actively bleeding or not do not allow transmission of HIV particles as if bleeding particles cannot get in and if not bleeding then are sealed. 

3 - The wounds that let the infection in would be large open wounds such as RTA trauma or medical procedures.

4 - My feeling nauseous and aching is not ARS but a coincidence.

5 - You don't thin testing is required - note i am in a long term relationship.

6 - Finally how does a needlestick injury transmit HIV if it superficial yet cuts cannot.

Thanks in advance for your final post.

1.  Correct

2.  Correct

3.  Even "large open wounds" rarely, if ever lead to infection.
